' 4|IvlPRovl-:Ivilsrn' IN HAMEQFASTENERS;

Specification-forming part of Letters Patent No. 198,951, November 24,1877.

dated J anuay 8, 1878; application filed To all whom 'it may concern:

Be it known that I, WILLOUGEBY MOFFAT, of Hornellsville, in the countyof Steuben and State of New York, have invented certain new and usefulImprovements in Rame-Fasteners, which improvements are fully set forthin the following specification and accompanying drawing, in whichjFigure lis a side elevation 5 Fig. 2, a plan or top view; and Fig. 3represents a vertical longitudinal section through the center of the Myinvention consists of a hame-fastening frame, arranged so that thelength of the connecting-strap may be conveniently adjusted, and havingjointed thereto a curved strapplate, provided with a recess ordepression, and a stub-tongue to receive and iirmly hold. the end of thestrap, in combination with a thumb-piece and s ring jointed thereto, soas to swing upon a center-pin, and provided at its lower side withprojections to limit its movement in the direction actuated by thespring, and with side projections on its upper side to limit itsmovement in the opposite direction, the inner sides of the thumb-piecebeing so formed as to catch over the side projections of the'curvedfastening, and thereby hold it iirmly and securely in position whenclosed, the arrangement being such that while the thumb-piece is heldinthe required position by the spring, so as to firmly keep the curvedholding-platein place when closed, it may be easily and quickly pressedback so as to release it, as will inafter shown. l

In said drawings, A is the hamefastening frame, which is made of metalor other suitable material. It consists of the sides a a', cross-bars bb', crossbar and studLtongue c, and back plate c.'

B represents the thumb-piece; d, the centerpin upon which its turns. Itis provided with a spring, dl, the ends of which, d2, press down againstthe back plate c', and the ends d3 press upward against the under partof the thumbby the thumb, be more clearly herepiece, as shown, (see Fig.3,) so as to force the upper part forward in the direction of the arrowE, Fig. 3

In operating it, it is pressed by the thumb or lingers on the part F,which moves it 'back in the position shown in Fig. l by the dotted linesF2, causing the parts j' f' to slip off from the side projections g onthe curved strap-plate Gr, thereby releasing it and allowing it to beopened back, as shown by the dotted lines F1, Fig. 1. g' is the joint onwhich it turns, and by which it is fastened to the frame A. It isprovided witha curved portion, h, a stub-tongue, h1, opening, h3,between them, through which the strap I is inserted, and the hole passedover4 the stub-tongue. The end is bent, as. shown in Fig. 3, so as tohold it securely. rPhe operation of closing it is simple, and will bereadily understood.

J represents the adjusting-strap.

4To decrease the length of the loop J1, remove the end of the strap atJ, push the end at J 2 under the bar b to the required distance; thenpull on the end of the strap J, replace it in position over thestub-tongue and through the box-loop. The short strap I is also passedthrough the box-loop, when the hame-ring is fastened in place by theclosing of the curved plate G, which may be done by pulling it shut bythe strap I with sufficient force to cause it to lock itself.

The centers d and g are .arranged in posi-- tion with reference to thestrain upon the parts,

as will be readily seen by reference to the drawing, so that the greaterthe strain the more securely it will be locked.

I claim as my invention- A hame-fastener consisting of the frame A, lthumb-piece B, jointed at d, andprovided with the spring dl, arrangedsubstantially as described, in combination with the curved strapplateG,as and for the purposes specified.

WILLOUGHBY MOFFAT.
